While testing Canon's cheapest lens on their highest resolution camera may seem to be a pairing of opposites, there is a point to be made here. The 50 STM is not a great performer at f/1.8, showing a "dreamy" look to be kind. If we review a comparison between the 5Ds R and 1Ds III with the 50 STM at its f/1.8 aperture, we see that the 5Ds R can extract more resolution from even a poor performing lens. Look at the white being more clearly delineated between the black lines in the top crop to most easily see this.

As same as the Live View mode of Canon “EOS 8000D (Rebel T6s / 760D)” and “EOS Kiss X8i (Rebel T6i / 750D)”, we have found that similar update is required for our lenses to make them compatible with the Live View mode of “EOS 5Ds” and “EOS 5Ds R” cameras.

Products and Serial Numbers to be updatedThe new firmware will ensure the lens is compatible with the Live View mode of EOS 5Ds and EOS 5Ds R cameras.

* For lenses that have been repaired in the past, they may require the firmware update even when the serial number is not listed above. If the mentioned camera does not display images on the rear LCD monitor when Live View Mode button on the camera body is pressed, it is necessary to update the firmware.* Our DC lenses are developed for the camera bodies with APS-C image sensor, and it is not designed for the cameras with full-size and 1.3x sensors.* There is no need to update the firmware of those products shipped after May 11th in 2015 or already updated for Canon “EOS 8000D (Rebel T6s / 760D)” and “EOS Kiss X8i (Rebel T6i / 750D)”cameras.

For those who own the SIGMA USB DOCK, it will be possible to update the firmware of 120-300mm F2.8 DG OS HSM | Sports through SIGMA Optimization Pro.

SANTA ROSA, CALIF – MindShift Gear’s First Light backpack series addresses the most pressing needs of outdoor photographers who travel and trek, especially those who carry their 200mm to 600mm “Big Glass” lenses. These high capacity backpacks come in three sizes and feature contoured, adjustable torso harnesses with 11 adjustment points for extreme comfort whether running through an airport or traversing a mountain. Designed to comply with airline carryon size requirements, First Light backpacks are built with ballistic nylon bottoms for durability, room for a laptop and personal gear, and in the two larger sizes, a dedicated pocket for hydration reservoirs.

“We heard loudly and clearly from outdoor photographers that they wanted dual-purpose backpacks they could use to transport their gear safely on airlines and also for carrying their largest lenses comfortably for hours while deep into their treks,” said MindShift Gear’s CEO and Lead Designer Doug Murdoch. “We were able to design backpacks sized to fit three different camera gear configurations that are the best made, most durable, most comfortable, and most reasonably priced in the market.”

Note: This is likely a grey market item and therefore technically ineligible for a Canon USA warranty. However, the auction advertises that a 1-year warranty is provided by the seller and is "...same as manufacturer warranty."

To be honest, I thought the 24-70mm f/2.8L II would be easy to declare the winner and optically, it is the best of this list. However, the two f/4 lenses perform better in front of 50.6 megapixels than I expected.

The f/2.8L II is slightly sharper over then entire focal length range at f/2.8 than either of the f/4 lenses are at f/4. At the equal f/4 comparison, the f/2.8L II is noticeably sharper and is still sharper at f/5.6. At f/8, the differences are slight and at f/11, diffraction essentially evens the playing field. Choosing an image sharpness winner between the two f/4 lenses is a challenge, but more noticeable is the 24-105's higher CA and distortion levels.

The f/2.8 lens has a 1 stop wider aperture, giving it the ability to stop action in 1/2 as much light as the other two lenses and the ability to create a stronger background blur. The 24-70mm f/4L IS rules the maximum Magnification (MM) spec with a 0.70x rating vs. the competition's 0.23x and 0.21x specs. The two f/4 lenses have image stabilization, allowing them to be used handheld in far lower light levels than the f/2.8 lens (as long as the subject is not in motion). The 24-105 L has the benefit of reaching to 105mm on the long end.

The f/2.8L II is slightly larger than the 24-105mm f/4L IS, which is slightly larger than the 24-70mm f/4L IS. The f/2.8L II has a modestly more substantial lead in the weight category, weighing in 5 oz (142g) more than the 24-105mm f/4L and 7 oz (198g) heavier than the 24-70mm f/4L. These lenses are similarly well-built.

Small differences between these lenses include the 2012-introduced 24-70mm models having 9 blade apertures vs. the 2005-introduced 24-105mm's 8 and the f/2.8 lens having an 82mm filter thread size (vs. 77mm). A not-so-small difference is the f/2.8L II's price relative to the f/4L IS models.

The Conclusions

All of these lenses are easily good enough for use in front of a 5Ds. The decision differences for many will come down to price, aperture and overall versatility.

If your investment in the 5Ds has left you monetarily strained, a good value may be your highest priority. In that case, the 10 year old 24-105mm f/4L IS, purchased in white box or refurbished condition would be a great choice. Canon omitted the 24-105 L from its EOS 5Ds Lens Recommendations List, but ... I think this model is very worthy of consideration.

If you need to stop action in low light or want to create the strongest background blur, you need an f/2.8 aperture and the choice is easy. While the 24-70mm f/2.8L II will impact your wallet the greatest and will leave you without IS, this is the most amazing lens choice optically.

For overall versatility, I'll give the nod to the 24-70mm f/4L IS. The smallest and lightest lens of the group, the 24-70mm f/4L IS offers great image quality along with the best-performing image stabilization system and a macro-lens-like close-focusing capability. While more expensive than the white box or refurbished 24-105 f/4L IS, the 24-70 f/4L IS has the same regular price as the 24-105 L and is also a good value.

The Ultimate 5Ds General Purpose Lens

While it would be easy to justify a decision for any of these three lenses, I'm going to declare the EF 24-70mm f/2.8L II Lens to be the ultimate EOS 5Ds general purpose lens. Canon apparently agrees with this choice as this is the lens shown mounted in the Canon-supplied EOS 5Ds product images. However, I will not be selling my 24-70 f/4L IS lens anytime soon.
